Exporting raster style to SLD only works when output file has .sld suffix

[NyakudyaA]

Problem

I have symbolized a raster layer and when I try to export it as an SLD it always saves it as QML.

@NyakudyaA cannot confirm here.

I will build again and test

I have the same problem. I'm using 3.10.5 on Ubuntu 18.04 and I can't create the .sld for a raster. I've tried to do the same with 3.4 on onother PC with Windows 10 and is possible to create the .sld.

@MaxDragonheart attach a sample of the raster you are styling as also the style in .qml format, thanks.

@gioman you can download the data here.

@MaxDragonheart this is the SLD I get in master:

seems pretty much the same as the one you attached.

@gioman here you can see what happen to me when I try to create an .sld
This happen only with raster layers; whit vectors I can create the .sld without problems.

This is my QGIS version

I can't replicate following the same steps on a different DM.

@gioman I can replicate. I have debugged what is happening

• When you try to export the SLD from master and you just write the name of the file it defaults to saving a QML.
• In the file selector if you choose a name like test.sld then you will actually get a valid SLD but without writting the extension it defaults to a QML

not on KDE. I haven't tested on Windows.

@NyakudyaA with your indication it is possible to create the .sld
